has written an interesting article on the the MPAA ratings systems and American Movie Classics use of the modern system to rate movies made before 1968, which theoretically should all be family friendly.
Lately, for about the last year, I have noticed American Movie Classics using MPAA-style ratings on movies made prior to 1968. You will see John Wayne westerns rated R. You will see family-friendly fare rated PG-13. In fact, nearly every old movie you see on this cable network is now rated R.
His thesis is something of a conspiracy theory, but it makes sense to me.

I wonder what rating AMC give Belles on Their Toes, with its kinky boyfriend in the bathtub visited by a slew of his girlfriend’s sibs scene?
